Challenges we ran into

The major hurdle was/is the limitations of the interactive infrastructure provided by WhatsApp, that majorly affects multi-step/multi-input processes.

To work around the hurdle, we explored determining the appropriate response to user actions using a combination of progressive IDs (for specific actions) and regex patterns (especially with interactive elements).

The pattern of the IDs is designed to track the next step using a set of identifiers from the previous step.

For example the progressive ID to sell USDC (BASE) to a beneficiary with ID: 123, looks like:

sell:usdc-base|beneficiaryId:123
